I-FLAC intsingiselo
I-Free Lossless Audio Codec yinkqubo yokunyanzelisa eyayiqulunqwe yi-nonprofit Xiph.org Foundation exhasa iifayile zomsindo zedijithali ezihambelana ngokucacileyo kunye nemvelaphi yendalo. Iifayile zekhowudi ezifakwe kwi-FLAC, eziqhelekileyo zithwala ukwandiswa kwe -flafla, ziyabonakala ukuba zibe nolwakhiwo oluvulekileyo-lwakhiwo kunye nobukhulu befayili kunye nexesha lokukhawuleza ngokukhawuleza.
Iifayile zeFLAC zithandwa kwindawo yokulahla engenakulahlekelwa. Kwizwi ledijithali, i- codec engenakulahlekelwa yinto engalahlekanga nayiphi na into ebalulekileyo yesignali malunga nomculo wokuqala we-analog ngexesha le-process-compress process. Amakhowudi amaninzi athandwayo asebenzisa i-compression-compression algorithms-umzekelo, ii-MP3 kunye ne-Windows Media Audio imilinganiselo-elahlekelwa ukunyaniseka kwomsindo ngexesha lokunikezela.
Ukusika iiCD zomculo
Enyanisweni, abaninzi abasebenzisi abanqwenela ukukhupha iiCD zabo zokuqala zomsindo (CD ukukrazula ) ukhethe ukusebenzisa i-FLAC ukulondoloza isandi kunokusebenzisa ifomathi elahlekileyo . Ukwenza oku kuqinisekisa ukuba ukuba umthombo wokuqala uwonakele okanye ulahlekile, ikopi epheleleyo ingenziwa kwakhona ngokusetyenziswa kweefayile zeFLAC zangaphambili.
Kuzo zonke iifomati zomsindo ezilahlekileyo ezikhoyo, i-FLAC mhlawumbi iyona ethandwa kakhulu namhlanje. Enyanisweni, ezinye iinkonzo zomculo ze-HD zibonelela ngeendlela kule fayili.
Ukukhupha iCD CD kwi-FLAC ngokubanzi ivelisa iifayile kunye nomlinganiselo wokunciphisa phakathi kwama-30 ekhulwini kunye nama-50 ekhulwini. Ngenxa yendlela yokulahlekelwa yintsimi, abanye abantu banqwenela ukugcina ilayibrari yomculo wedijithali njengeefayile zeFLAC kwimidiya yokugcina yangaphandle kunye nokuguqula amafomathi alahlekileyo ( MP3 , AAC , WMA , njl njl.) Xa kufuneka-umzekelo, ukuvumelanisa kwi- MP3 umdlali okanye olunye uhlobo lwefowuni ephathekayo.
Iimpawu zeFLAC
Umgangatho we-FLAC uxhaswa kuzo zonke iinkqubo ezinkulu zokusebenza, kuquka i-Windows 10, i-MacOS ephezulu yeSierra nangaphezulu, ininzi yeeLuxux, i-Android 3.1 kunye ne-entsha, kunye ne-iOS 11 kunye ne-entsha.
Iifayile zeFLAC zixhasa ukuthayipha imetadatha, ubugcisa bokubamba i-albhamu, nokufuna ngokukhawuleza umxholo. Ngenxa yokuba ifomathi engenazo iimpahla kunye neelayisenisi-ntlawulo ye-core core, i-FLAC ithandwa kakhulu ngabaphuhlisi abavulekileyo. Ngokukodwa, ukuhanjiswa okukhawulezayo kwe-FLAC kunye nokuqulunqwa kwemilinganiselo kuthelekiswa nezinye iifom ukwenza ukuba kulungele ukudlala kwi-intanethi.
Ukususela kumbono wobuchwepheshe, i-encoder yeFLAC isekela:
- Izinga lokusampula phakathi kwe-1 Hz ukuya ku-65,545 i-Hz kwi-1 Hz amanyathelo, okanye i-10 Hz ukuya ku-655,350 i-Hz kwiimitha ezili-10 ze-Hz, usebenzisa iisithuba ezilishumi kunye nesibhozo
- Isisombululo sesincinci se-PCM sesine-4 ukuya kwi-24 ngeesampula (nangona kuphela i-point-fixed-point, kunye ne-point-floating-point, iisampuli ziyaxhaswa)
FLAC Imida
I-pullback engundoqo kwiifayile zeFLAC kukuba i-hardware eninzi ayixhasayo. Nangona iinkqubo zekhompyuter kunye neye-smartphone ziye zaqala ukuxhasa inkxaso ye-FLAC, i-Apple ayizange ixhase kuze kufike ngo-2017 kunye neMicrosoft kuze kube ngu-2016-nangona kunjalo ukuba i-codec yaqala ukukhutshwa ngo-2001. Abadlali bezinto eziphathekayo ngokubanzi abaxhasi i-FLAC, kunokuba baxhomekeke ekulahlekeni- kodwa ifomati eziqhelekileyo zifana ne-MP3 okanye i-WMA.
Esinye isizathu sokuba i-FLAC inokuthi ithatyathwe ngokuthe ngcembe kwishishini, nangona ubukhulu bayo bunjenge-compression algorithm, kukuba ayixhasi naluphi na uhlobo lolawulo lwelungelo lwamalungelo edijithali. Iifayile ze-FLAC ziyi-design, ezingenakunikwa izicwangciso zeelayisenisi ze-software, eziye zanciphisa ubuncedo bayo kubathengisi beentengiso kunye nezoqoqosho kumashishini omhlaba wonke.
